A CORPORATION OF NEW JERSEY.

CAN-BODY-MAKING MACHINE.

Specification of Letters Patent.

Application filed February 11, 1907. Serial No. 356,706.

T 0 (LR whom it may concern:

Be it known that I, EDWIN V. SWANGREN, a citizen of the United States, residing in Haywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Can Body Making Machines, of which the following is a specification.

My invention relates to improvements in can body machines, and more particularly to improvements in the side seam soldering mechanism of lock seam can body making machines.

In automatic lock seam can body making machines heretofore in use, the lock seam of the can body is customarily soldered by moving the can body continuously along a soldering horn extending from the body former horn so that the side seams of the can bodies will come in engagement with one or more soldering irons or shoes mounted above the soldering horn and closely adjacent thereto or resting thereupon, or else by moving the can bodies continuously along over a soldering bath or soldering devices mounted beneath the path of the can bodies and with which the side seams of the can bodies come in contact as the can bodies are fed or moved continuously over the soldering horn. In can body machines of both these types, the inside'surface of the can body at the side seam is more or less coated or smeared with solder which is objectionable, rendering the cans more or less unfit for use as preserving cans for many food products, and also because of the large amount of solder required in soldering the seams as the solder coating or smearing on the inside surface of the can body adjacent to the seam adds nothing to its strength or security. In that type of machines which employ the solder bath or molten solder applying devices below the path of the moving can bodies, a short are of the can body adjacent to the side seam is ordinarily immersed in the molten solder, or the molten solder is caused to flow upon the inside of the seam. And in the other type of machines in which the soldering is done from above, the solder, whether fed seam and gets upon the soldering horn beneath the seam and tends to smear or coat the inside surface of the can body adjacent to the seam as the same slides along the horn.

The object of my invention is to provide an improved construction of lock seam can body making, or can body forming and soldering machine in which the soldering of the side seams may be done rapidly and economically or with a minimum amount of solder and by which the inside surface of the can bodies, either adjacent to the seam or elsewhere, will not be coated or smeared with the solder.

My invention consists in the means I employ to practically accomplish this object or result. That is to say, it consists in con nection with the former horn, body formers and bumper, of a lock seam can body machine and a soldering horn extending therefrom, of an intermittently moving feeder or carrier for advancing the can bodies along the soldering horn by a step by step movemerit, and one or more, preferably a plurality of vertically movable and horizontally reciprocating soldering irons or shoes operating upon the side seams of the can bodies while the same are stationary or at rest, and one or more, preferably a plurality of solder feeders, preferably solder wire feeders, operating to feed or apply the solder to the can body while it is at rest, the soldering horn having a slot or cut away portion under the soldering iron or shoe so that the soldering horn itself will not become coated or smeared with molten solder. In practice, the solder wire feeders feed measured lengths of solder wire under the face of the soldering iron or shoe while the same is in its raised position, the hot soldering iron or shoe melting the portions of the solder wires beneath it as it moves downward into contact with the side seam of the can body on the soldering horn.

My invention also consists in the novel construction of parts and devices and in the herein shown and described.

In. the accompanying drawing forming a part of this specification, Figure 1 is a side elevation of a lock seam can body making machine embodying my invention, the same, however, showing onlythat portion of the completed machine to which my invention particularly applies. Fig. 2 is a plan'view Patented Nov. 15, 1910.

novel combinations of parts and devices with soldering horn removed. Fig. 3 a detail longitudinal section partly in elevation. Figs. 4, 5 and 6 are vertical sections on lines le-4, 55 and 66 of Fig. 2. Fig. 7 is a detail plan view showing the wire solder feed devices, and Fig. 8 is a detail elevation of the wire solder feed devices shown in Fig. 7. 9 is a detail View of parts hereinafter described; and Fig. 10 a detail section showing the wire solder feed rolls.

In the drawing, Arepresents the frame of a lock seam can body making machine, B the body former horn, B the body formers or devices for wrapping the flat can body blank around the horn and C the bumper. These parts may be of any well known kind or construction commonly in use and familiar to those skilled in the art.

D is the soldering horn extending from the end of the body former horn B and upon which the can bodies are supported and guided as they pass off the body former horn B and are conveyed along to the fluxing and soldering devices. The soldering horn D is preferably of a skeleton form and made up of parallel bars (Z with an open space of slot (Z between the tow uppermost bars cl (Z. This longitudinally extending open space d registers with the lock side seam groove 1) of the body former horn B and the width of this slot d is wider than the lock seam 00 of the can body X, and preferably somewhat wider than the thickness of the face 7 of the Vertically movable and horizontally reciprocating soldering irons or shoes F so that the soldering horn will not feeder of carrier by which the can bodies j are moved intermittently or by a step by come in contact with the soldering iron or shoe F whether a can body is present or not beneath the soldering iron and so that the soldering horn will not operate to draw the melted solder through the lock seam onto the. inner surface of the can body, or to smear such inner surface of the can body with solder by reason of the soldering horn itself becoming smeared with the solder from the soldering iron above. The inner end of the soldering horn D is connected to and supported from the body former horn B. Its outer end is preferably furnished with a roller (Z and rests upon the horn supporting roller (4 on the frame A of the machine so that the soldered can bodies can pass off the horn.

The soldering irons or shoes F are preferably three in number and are mounted so as to be capable of a slight up and down movement to enable the can bodies to be advanced along the horn beneath them by an intermittent or step by step movement, and are given a horizontally reciprocating movement in the direction of the can bodies to properly heat the seam and sweat the solder into. the same.

E is. an, intermittently. moving can body step movement along the soldering horn from the body former horn B. This intermittently moving or step by step carrier for the can bodies consists preferably of a pair of reciprocating feeder bars furnished with a series of fingers or pawls E for engaging and pushing the can. bodies along, the pawls or fingers E preferably having springs E to enable the pawls or fingers to close out of the way when the reciprocating pusher bars make their backward or return stroke,

G is the fluxing device, the same being preferably mounted on. the frame of the machine above the soldering horn and consisting of a brush or padarranged in the path of the side seams of the can bodies as they. are moved along the soldering horn and upon which acid or other suitable flux is fed from the flux tank G through a nozzle 9.

H is the solder feeder or device by which the solder in measured quantity is fed to the seam of each can body while it is at rest on the horn under the first soldering iron or shoe F. The solder is preferably fed or applied in the form of wire solder, and the feeder H preferably consists of a feed roll suitable for feeding this form of solder. The wire solder feed device H is preferably furnished with a plurality of grooves h for feeding a plurality of solder wires y from the solder wire reels or spools Y. i To give the Wire solder feed device or roll H the requisite grip upon the solder wires, I provide a plurality of cooperating solder feed rolls H each mounted upon an arm or lever H and. furnished with a spring H to press the roller H against thesolder wire and feed roll H. The solder wires 3 pass through wire solder guides H whichv serve to guide or directthe ends of the solder wires between the soldering iron F and the side seam of the can body to be soldered which is on the soldering horn D below the first soldering iron, F so that when this soldering iron F is again lowered against the seam, the portions of the solder wire which are fed or projected under the soldering iron will be melted thereby. The solder .wires y pass from the spools Y over a guide roller H Each of the vertically movable and horizontally reciprocating soldering irons F is furnished with a heating chamber F and'is secured to an arm F having a pivotal or hinged connection F with a reciprocating slide or rod F by which the soldering iron is given its reciprocating movement, the hinged or pivotal connection F with the slide or rod F adapting the soldering iron also to receive the necessary slight up and down or vertical movement to enable the can bodies to be slipped along the soldering horn D under the soldering irons when they are in their raised position. The soldering irons F or their carrier arms F are preferably intermittently raised and lowered as required or given the necessary up and down movements by means of a reciprocating slide 7' furnished with inclines or cams which engage rollers on the hinged arm F of the soldering iron. The arms F are preferably connected to the heating chamber F of the soldering iron F by connecting brackets F The slideor bar 7" is preferably intermittently reciprocated as required by means of a cam on on a cam shaft M of the can body making machine through a connecting link m bent lever orrock shaft m" and connecting link The reciprocating slide or rod F by which the soldering irons F are given their re quired horizontally reciprocating movement is preferably intermittently reci )rocated as required by means of a cam m on the M through a connecting link m, rock shaft or bent lever m, and connecting link m The intermittently moving can body feeder or carrier E may be given its required reciprocating movement in any suitable manner as, for example, by a sprocket gear at on the shaft lvl through suitable connecting links and levers m2 m in crank m sprocket gear m and sprocket chain m.

Thesolder feeder or roll H is given its required intermittent movement preferably a from the can body feeder or carrier E through a connecting pawl or trigger 71 which is adapted to engage a notch or projection c on one of the reciprocating bars of the carrier E and which is pivotally connected by a pin 11 to an arm 71 on a rock shaft h having an arm if which is pivotally connected at h with an arm 7L pivotally connected at 71: with a bent lever 71 carrying a pawl 71. which engages a ratchet h on the shaft h which is furnished with a bevel gear 72 meshing with a bevel gear h on the shaft h of the wire solder feed roll H. The bent lever 72-" carrying the pawl 71?" is also preferably furnished with another pawl 71 spaced a half tooth of the ratchet from the pawl It so that the lever it may be given a stroke of half a ratchet tooth and thus give the ratchet a half tooth turn. To regulate the stroke of the pawl lever 72 and the extent of feed of the solder wire. the link or arm 71? has an extension 72" furnished with an adjustable stop or screw h. A spring 71, serves to retract tl e arm ]L3 of the rock shaft h*. The trigger or pawl h is normally held out of engagement with the projection c of the carrier E by a spring h and it is moved into position on the back stroke of the carrier E to engage such projection e on the carrier on the next forward stroke of the carrier E by the can body X on the soldering horn D. in case a can body is there present under the first soldering iron shaft 1* to so move the trigger /LL when the can body carrier E moves backward. As the trigger h through which motion is communicated to the solder wire feeder is thus automatically moved into position for operation by the can body itself, it necessarily follows that unless a can body is in position on the soldering horn I.) under the first soldering iron F to receive the solder, the wire solder feeder will not be operated and no solder will be fed. By thus providing the solder feed actuating mechanism with a trigger operated by the can body itself, the solder is only fed to the can body when a can body is present to receive it.
